  1. I think class A farmland gives a better cash return than a solar farm, so only an idiot would swap farming for PV. (Caveat, most farmers lease the land to solar developers, they don't pay for the PV themselves). Hard to grow crops under a PV panel so any grazing is of low stock density, which is an uneconomic method if farming. As much as I like the idea of making it compulsory for new builds to have PV, many buildings will not be suitable (wrong angles and shading). There is the grid reinforcement costs to upgrade a lot of old buildings, which may also suffer the same problems as above. There is plenty to suitable land for farming, PV, Wind farms, housing and industry in the UK, just as there is plenty of land for golf courses and motor racing circuits, small air parks, military based and bus depots. We just need to allow people to develop sites and get grid connections in faster and cheaper (so don't force it to planning appeals all the time). How about open public voting, so we know who is for or against. If against the power companies can reduce your fuse size, say down to 30A, then 20A if you still vote against a development. It does seem odd that you can vote against a national infrastructure project which affects other people and not have any personally responsibility for the outcome.
  2. Now thats a really good idea. Green burial probably releases less CO2e
  3. From memory, and it is a fair few years since I was involved, and terminology changes, it is to do with the amount of overall capacity and the number of participants joining the auctions. So say on a typical day, in November, you have 500 people joining the action to either sell their generation, or buy a slot they hope to fill, and compare that to a really sunny June day when PV generation may be high, so there is capacity to dump (sell) but not many slots to fill (buy) as overall capacity needs to be lower, that day may have 1000 people entering the auction. Over the year, it therefore means that 50% of the buy, or sell, bids fail. Another way to think of it is as a sealed bid auction. some houses may get 100 bids, another 1 bid, with the overall average say being 30 bids per house. If there is lots of cheap money, the average number of bids per house may go up to 45 (50% higher). This would give a quirk that could be seen as excess demand (more bids at higher prices), but if you look at the supply side (and you have to with electrical generation), the number of houses for sale may be the same, or lower. That's is basically what Game Theory does in a public auction, it is not a case of the winner takes all, more a case of more people spreading the total load (I think in the movies, Beautiful Mind, the most desirable girl, that all the boys lusted after, did not get taken home, but everyone else were matched up, so one loser but many people still satisfied). So the most competitive may not always win, as the auctioneer needs to keep a number of players in the market, or a monopoly, duopoly, oligarchy or other limited number of suppliers can arise, and that is not good for reliability, prices, environmental considerations, bulk power transportation (which is possibly why they turn of some of the capacity) and other reasons.
  4. Why is it wrong? Or is that just your opinion? Worth looking up Game Theory and John Nash. Spend a few hours down this rabbit hole. https://www.nationalgrideso.com/what-we-do/electricity-national-control-centre/what-balancing-mechanism
  5. I had a girlfriend who was a 'saver', I always knew how much she had saved, it equalled my overdraft.
  6. Which calories though? Called a crematorium with CHP.
  7. That is also a good way of extending credit.
  8. Or multiples of joules, which is what we should really use, then there is no confusion.
  9. Because it is cheaper to turn of a few MW of wind generation than shut down and restart a large gas powered generator (which also gets paid for non generation). It is all do do with the Balancing Mechanism Auctions. They have proved to be the cheapest way to deliver power. The alternative is to constantly over or under generate, and disconnect or incentives consumers (what Octopus is playing with). There are very clever engineers, statisticians, economists, accountants etc that work on keeping the UK powered, they will know if any deal you think up is viable or not. I think what you are actually after is a good deal for yourself, not for the nations energy grid. Take your idea of a 3.3 MW (installed capacity) solar farm, in the scheme of things it is tiny, but say it went ahead and you entered the market as a generation company (so either guaranteeing a fixed supply, or bidding in the day ahead auction). Two simple scenarios. You oversupply on a rare sunny day and are asked to disconnect You undersupply and you are asked to fill in the gap What sort of commercial deal you willing to do? (You can look up the prices on the web)
  10. Donald Trump does, he sees value in everything that suits himself.
  11. Was their first DJ. Think he ended up on the Beeb.
  12. Our @joe90 had some wind driven water problems on his new build, he had used a full fill mineral insulation that could cope with getting wet, and treated the outside brick. Cured the problem.
  13. As you lot probably use, or at least aspire to use Crapple products, why piss about, just get their latest toy. https://www.apple.com/uk/apple-vision-pro/
  14. Had Princess Anne tour our factory, she is now an expert on material testing machines, and we got the Queen's Award for Export. She looked elsewhere, mainly her watch I seem to remember.
  15. Why not put in a larger MVHR system that can cope with moving greater amounts of air about? There seems to be a fixation that MVHR can never be used for effective cooling. It may not be the most cost effective method, and probably harder to install, but buildings all over the world have used forced air heating a cooling, except in the UK, where we like to think we are World Class and know best.
  16. I was in a traffic jam for 4 hours yesterday, there was a (expletive deleted) in a campervan that decided that we all needed to enjoy his music. Even, at full volume, The Archers theme tune did not drown his racket out.
  17. I published an article about this over a decade ago, I wonder if read it. There are some advantages of small, local storage in that the grid does not need reinforcing and the individual unit prices are low, so it is a very scalable system.
  18. I am not as visited my mother today. Now I am stuck on M5 as it is closed both ways. Going to be a long journey home, been in the car 11 already.
  19. To me, it seems to be just a net billing system (as long as the exports are greater than the imports). Probably be pulled from the market as I suspect that Octopus are just testing the market. For them it is very cheap market research, the customer is doing a lot of the work.
  20. Nice soundbites from Greg, but he does not say how you get customers to use energy when he wants. Nor does he mention local grid reinforcements.
  21. What was the demand back then? We build 2,107,430 houses in the 1980s. That is a little bit more than the 1990s and 2000s. (I actually not sure I know what you mean, but the data of house building is available for all to see on the ONS website)
  22. Does that mean that world class British fruit is not the export miracle the world was craving, but was stopped because of vicious Eurocrats.
